Question

Is there a benchmark on how much faster GPU-based simulation is for different solvers? all I see in the official thread is that it will 'significantly speed up the simulation'.

Hello

This is work in progress. We are currently able to assemble the system on the CPU and solve it on the GPU. Our next step is integrating both on the GPU.
What do you need the benchmark for?

I am choosing a tool for a set of Thermo-Mechanical Solves, and I wanted to test both MOOSE and MFEM on GPU. Just wanted to know if there was a baseline performance profile I could work off of.

Also happy to get involved in the discussion of integrating both on the GPU, if there's a thread you can point me to.

I think you'll find a lot more implemented CPU capability here than you will find with MFEM on the GPU. It depends of what you need in terms of physics & models.

There is no public project afaik, GPU support is being developed internally.
